+
+## CRITICAL INSTRUCTIONS - MUST FOLLOW
+
+1. **Simple commits**: One-line commit messages ONLY. NEVER add "Generated by Claude" footers, emojis, or any multi-line messages. Just describe what changed in one line.
+
+2. **Minimal comments**: Only add comments when absolutely critical for disambiguation
+
+3. **Never use `go build`**: Always use `go run` instead of `go build` for testing Go programs
+
+4. **Never change directories**: Never change directories with `cd` - always use absolute paths instead
+
+5. **Error handling**: Always propagate errors with proper messages, never silently handle errors
+
+## Project Overview
+gocp is a Go MCP (Model Context Protocol) server that provides tools for building and executing Go code. It uses the go-mcp library to implement the MCP protocol.
